, Be' t'known that L'Lours H. BRINKMAN, a

citizen of the United States, residing at West Hartford, in the-[county of Hartfordand State'of. Connecticut, have invented a new and useful Improvement in Radiators, of which the following is a specification, accompaniedbydrawings forming a part of the same, inwhich.

Figure 1 represents a frontelevation' of a radiator embodying my invention. Fig. 2 is an end v ew shown n sec-tionon line v,1. F1 3 is Fig.

cha'mber s. Fig. 4 IS an enlargedtop view of a portion of the radiator with the upper waterwchamber removed, and Fig. 5 is a detached and top .vi-ew of two pipes having overlapping coils.

- Similar-reference letters" and figures refer,

to similar arts in the different views.

The ra'iator forming thefisubject of my flpresentiirventioni designed to be used with either. hot; water or steam for heating purposes "or" for cooling water heated by the cy inder of an explosive-engine-such, for ex ample; as the-.gosolene-engines employed in automobiles; and. the objects of my inven tion are to increase-theradiating efficiency in a device of-.thisiclass, to simplify its coni.

struction, and reduce the cost; and my inventioii consists .inthe construction and ar rangement of partsas hereinafter described, and pointed out in the annexed claims.

Referring tothe accompanying drawings, v

1 and 2 denote upper and lower chambers,

having pipe connections 3 and 4 for the admission of either steam or water, as may be required. Pipe 4 communicates directly with chamber 2; but pipe 3 communicates with a compartment 5, separated from the into the chamber 1.

chamber 1 by a partition 6, having a series of holes 7, (represented by broken lines in Fig.

1,) forming a communication between the compartment 5 and the chamber 1. The area of said holes 7 is substantially equal to that of the pipe 3, so that Water admitted through the pipe 3 will first be received in the compartmentfi and pass through the holes 7 The purpose of the holes 7 is to secure a more uniform distribution of water received through the pipe 3 1n Specification of Iietters P- atent.

the chamber 1. The chambers 1 and-2 are connected at their ends by plates 8, having fnarrow flanges 9. The chamber 1 communicates with chamber 2. by means of a series of spirally-wound-sheet-metal pipes 10 and 11,

pipes 10 being Wound with a right-hand spiral and the alternating pipes 11 being wound witli aleft-hand spiral.

The spaces 1212 between the successive coils of pipe are slightly reater than the diameter'of the pipe, and t e coils of each spirally-wound pipe are inserted between the coils of'tlie adjacent spirally-wound pipes, thereby causing the several coils of the right and left hand spirally-Wound pipes to overlap, as-shown in Figs. 1 and 3, with the coils of each pipe 10 in contact with the coils of the adjacent pipe 11. The coils of adjacent pipes are overlapped sufficiently to provide an intervening space '13, through which is longitudinally inserted a metallic strip '14,

ernately wound in reverse spirals, the I provided with flanges 15 at its upper and I lower ends, by which it is'attached to the bottom of chamber 1 and the top of chamber 2.

The strip 14 is of sufficient width to bring its opposite edges into contact with the overlapping'coils of both pipes 10 and 11, so it.

will become heatedby its contact with the pipes.

v The upper ends a of the coiled pipes are inserted in the bottom 16 of chamber 1 and securely soldered thereto, and the lower ends I) of thepipes are -similarly inserted in the top 17 of. chamber 2 and are soldered thereto. The sheet-1netal plates forming the bottom 16 and top 17 of the chambers 1 and 2, to-

e'ther with the ends of the coiled pipes soloered thereto, having metal strips 14 inserted as described, are then submerged bodily in a bath of liquid metal, such as tin or solder, by which the contacting surfaces of all the coiled pipes and metal strips 14 become soldered together, forming a rigid structure. The sheet-metal shells 18 and 19 are then at tached to the plates 16 and 17 to inclose the chambers 1 and 2. The upper chamber 1 is provided with a capped nozzle 20 to allow the radiator to be filled with Water, if desired,-

and when the radiator is to be used withsteam a vent-cock 21 may be provided, if de sired, for the escape of air.

When my improved radiator is used in.

cooling the water in connection with an ex- 1 I plosioneenginc such as the engine of an autowater from the engine ed water 1nobile,for eXalnplethe pipes 3 and 4 are from the compartment 5 into the chamber 1 through the series of restricted openings 7, l

by which the proper distribution of the heatthroughout the chamber 1 is secured. The heated water from chamber 1 flows downward through the'series of coiled pipes and 11 into the lower chamber 2,

from which it is returned to the engine ator may be made thrdugh thev pipe; 4. 'The plates 16 and 17 are preferably flanged at22 to facilitate the attachment of the shells 18 and 19, which inclose the chambersl and 2. The entire radifrom sheet metal, like copper or brass, which will permit the rapid radiation of heat, and all the joints are united I by soldering orbrazing, thereby rendering-the inclosed spaces for steam or water absolutely tight with out packing. The series of coiled pipes are repeated across the front of the radiator in sufficient number to give the'desired width to the radiator, and the rows of coiled pipes may be multiplied to any extent desired, two of suchrows being shown in Fig. 2 of the drawings, the number of coiled pipes and the number of rows being determined by v the amount of radiating-surface required.

vBy overlapping the coils of adjacent pipes the space required for the several rows of ipes and each row of pipes is considerably essened, and as the. overlap ing coils are brought closely together and each coil is soldered tq theadjacent contactin coil the radiator is rendered extremely rigi I also increase the rigidity of the radiator and resist anystrains which would break the soldered joints between the. adjacent coils of pipe by the insertion of the metal strips 4.

The metal strips 14 also increase the area of radiating-surfacepas the edges of the metal strips. 14 are brought into contact with and soldered to the inside of their inclosing'coils.

{ What I. claim as my invention, and desire l to secure by Letters Patent, is-

' 1. In a radiator, the combination with upper and lower chambers, of a series of coiled l pipes communicating at their ends with said 1 chambers, and having coilso'f adjacent pipes j overlapping each other and a metal strip inserted longitudinally through said overlapping coils.

I 2. In a radiator, the combination with upper and lower C-llillllbIS, of a series ei co led i pipes communicating at their ends with said chambers, and having the coils of adjacent l pipes overlapping, and a metal strip inserted l longitudinally through said overlapping coils l with its edges attached thereto.

3. In a radiator, the combination with up per and lower chambers, of a series of coiled pipescommunicating at their ends with s;

i chambers, with the coils of adjacent pipes overlapping each other, and a metal strip inserted between said its ends attached to said chambers.

4. In a radiator, the combination of a series of spirally-wound pipes having the coils of adjacent pipes overlapping each other, and a metal strip inserted longitudinally through said overlapping coils.

5. In a radiator, the combination of a series of spirally wound "pipes alternately wound in reverse order with the coils of adjacent pipes overlapping each other, and metal strips inserted through said overlapping coils and in contact therewith.

6. In a radiator, the combination with an upper and a lower chamber, and a series of connectingpipes btween said chambers, of a separate compartment in said upper chamber and extending the entire length of said chamber and at the upper corner having a series of restricted openings leading from said compartment to the upper part of said upper chamber, and an admission-pipe leading to said compartment.
